The rotary trademark printing machine can print self-adhesive labels, that is, various labels. It can be printed in multiple colors and the printing speed is fast. It can only be roll-to-roll.

The development status of rotary trademark printing press

Full rotary trademark printing is a printing technology that has developed rapidly in recent years. Its equipment principles and printing technology have gradually been recognized by the industry. In the Asia-Pacific region, there are three full-rotation equipment suppliers in Taiwan

LABELMEN (Luotie), Japan's TAIYO and

KOPACK. At present, there is no such production capacity in China. The growth of the global label industry is becoming a driver of the sales industry. Labels are widely used in all aspects of public life and production. With the development of the domestic economy, the market's precision and technical requirements for label printing have also shown a trend of high standards and diversification. , especially trademark printing.

Resin plate trademark printing has gradually evolved from the popularization of flat flattening and round flattening equipment to intermittent trademark printing. As market end users have higher and higher requirements for trademark printing technology, and a large number of special printing The promotion and application of materials have greatly limited and restricted intermittent trademark printing technology.

Different from flexographic printing, the printing speed of full-rotation trademark printing can reach 100 meters per minute, and the printing formats are 260mm and 460mm. It is no longer a simple 4+1, 6+1, 12+1 color printing color sets. Full rotary trademark printing has on-line printing, UV drying, UV local varnishing, and even die-cutting

(two methods) integrated operations of hot stamping and cutting. The printed product can be completed in one go. Its technology It is widely used in trademark and label fields such as food and beverages, cosmetics, washing and daily chemicals, high-tech electronics industry, cartons, medicines, alcohol, battery labels and other fields.

The application of tension control system and high-speed flat-cut die-cutting technology has made full-rotation trademark printing more promising. It is more flexible and convenient than offset printing and gravure printing. Each printing base is equipped with a UV drying system to realize printing and varnishing operations, while ensuring the color image, firmness, wear resistance and other standards of the printed product, reducing the cost of printing. The coating amount of ink and varnish is reduced, and it fully complies with environmental protection requirements. In addition to round-cut magnetic hob die-cutting, full-rotation trademark printing uses flat-cut equipment that fully matches the printing speed, further reducing the industry's production costs and die making time, whether it is large-volume long-line production or small-scale production. It can be used freely in batches of short-line operations and fully ensures the flatness of the printed surface and the neatness of the cross-section.

The full-rotation trademark printing machine can also solve the problem of 1-mil-thick low-density polyethylene film and PE, heat shrinkable film, and environmentally friendly composite materials that cannot be effectively processed by unit-type (intermittent) rotary machines. , film-in-film stickers, electrostatic films and other materials with higher ductility. This usually involves using its automatic unwinding tension system with a tension detection roller equipped with label material. When the material rotates through the printing press, the preset tension will be maintained on the roller regardless of the size, width and rotation speed of the label material. The tension sensing device continuously monitors the tension of the trademark material and corrects it simultaneously if any tension changes. When the label material reaches the upper and lower limits, the printing machine will automatically stop working. At the same time, the roll-out part is equipped with an automatic compensation tension control system, thus effectively ensuring that the printing crystal will not affect the accuracy of color registration due to tension.

At present, the main problem of full-rotation printing is the printing of vignetting (vignetting). When the dots are less than 5%, good printing results can be obtained, but the printing process requires frequent shutdowns for plate washing. , the operator can handle several aspects such as the printing amount, concentration and uniform ink pressure of the ink. Full-rotation trademark printing technology is increasingly accepted by the majority of industries. The difficulty and diversified requirements of end-users for trademarks have also been successfully solved with the promotion of full-rotation printing technology.
